It sure look like it, yeah.  Or something similar.  This suspect this
test case exposes the problem:

  perl -Mstrict -Mwarnings -e \
    'use fields; my $self = {}; $self = fields::new("fields"); $self = bless $self, "fields";'

When using perl 5.10, I get this error:

  Modification of a read-only value attempted at -e line 1.

With perl 5.8.8, I get no error.

I guess the $self content someone is read-only with perl 5.10.

Happy hacking,
